Outdoor prefabricated substation

Abstract

The invention discloses an outdoor prefabricated substation which comprises a frame, the frame is provided with an external support, a filter layer is arranged in the support, arc-shaped anti-collision beams are symmetrically arranged outside the support, anti-collision rods are connected between the anti-collision beams, the ends of the anti-collision beams are hinged to the rod ends of cylinderbodies, the cylinder bodies are fixedly connected to the frame, and baffles are arranged outside the anti-collision beams. Shielding plates are arranged at the upper parts and the lower parts of the baffles. A fan is arranged on the lower shielding plate in a penetrating mode through a cylinder frame, a folding plate is arranged between the anti-collision beams and the frame, preassembled supporting legs are arranged at the bottom of the frame, positioning bases are arranged on the inner sides of the supporting legs, four snow accumulation preventing roofs inclining downwards are arranged at the top of the frame, and a door plate and a back plate are movably arranged on the front side and the rear side of the frame respectively. Elements are convenient to install and overhaul through the back plate and the door plate, the anti-collision beams avoid frame deformation damage caused by external force collision, a filter layer reduces dust and water content of entering air, the fan ensuresair in the frame box body to be communicated with the outside, internal temperature is reduced, the supporting legs are used for pre-installation, and a positioning seat is convenient to position, install and fix.

Description

technical field

[0001] The invention relates to the field of electrical technology, in particular to an outdoor prefabricated substation. Background technique

[0002] Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. According to the size, the small ones are called substations. A substation is larger than a substation. Substations generally refer to step-down substations with voltage levels below 110kV; substations include "boost and step-down" substations of various voltage levels.

[0003] In order to reduce the footprint of substations, sulfur hexafluoride hermetic combined electrical appliances (GIS) are widely used. It installs circui...
